TURPENTINE-CONDENSER.

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed December 4, 1915. Serial No. 65,103.

To all whom it may concern:

Be it known that I, ARTHUR H. BAKER, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented new and useful Improvements in TurpentineCondensers, of which the following is a specification.

In the process of distilling, there is a certain amount of vapor that escapes from the condensing worm with the condensed spirits, and passes into the atmosphere and is lost.

My invention is designed .to provide an auxiliary condenser which is connected with the tail of the ordinary condensing worm and receives and holds this escaping vapor, condenses it and at the same time cools the spirits before reaching the air, so as to prevent the losses which occur from the evaporation into the air of a portion of hot spirits which commonly occur.

The invention is further designed to provide a turpentine condenser which is simple of construction, reliable and etficient in operation, and which may be operated without adding to the normal cost of production.

The invention'consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawings in which Figure 1 is a view in side elevation showing the application of the invention to a turpentine still. Fig. 2 is a top plan view on an enlarged scale of the condensing tank, the cover thereof being removed to disclose the arrangement of the condensing drums therein. Fig. 3 is a perspective view of the drums removed from the tank. Fig. 4 is a sectional perspective view through the drums and showing the water supplying connections. Fig. 5 is an inverted sectional perspective view of one of the drums.

Referring to the drawings, 1 designates a. still kettle, 2 a still worm or condenser, and 3 my improved auxiliary condenser, which is connected with the tail of the worm 2. 1

As shown the condenser 3 comprises a water tank or receptacle 4, receiving the condensing elements of the auxiliary condenser, which elements consisting of drums and connecting pipes are normally submerged in the water contained in the tank and cooled thereby. In practice, the two condensers may be cooled by the same body of water, but this is not essential.

-The condensing elements arranged within the tank 4: consist of a pair of receiving or primary drums 5 and and a pair of delivery or secondary drums 6 and 6. The drum 5 of the receiving pair is provided at one side with an inlet pipe or tube 7 which is connected with the tail end of the worm 2 and receives the spirits, vapor and water of condensation there-from. The tank 5 is connected with the tank 5 by upper and lower connecting tubes or pipes 9 and 10, and the drum 5 is connected with the drum 6 and the drum 6 with the drum 6* through similar pipes or tubes, the final drum (5 having at its top an air discharge outlet 11 and a spirits discharge outlet 12. The pipes 9 connect the upper or vapor spaces of adjoining drums and the pipes 10, the lower or condensates containing spaces of the drums, and these pipes are preferably made rectangular or flat in cross section so as to expose as much surface to the water as possible for a cooling action.

Each drum comprises a cylindrical vessel 13 within the body of which is arranged a condensing dome 14. This dome 14 is of less diameter than the vessel 13 and extends upwardly thereinto to a point just below the horizontal center of said vessel 13 and in substantial alinement with the condensates discharge pipe or tube 10. The interior of the dome 14: which is closed against communication with the vessel 1 is filled wlth water, and thus presents an lncreased area of .cooling surface within tl'iereceptacle 13 to 'to a level between the level of the pipes 9 and 10. said partition having at its ends depending portions which project down into the annular space between the side walls of the vessel 13 and drum 1% and thus divides the lower portion of the drum into inlet and exit chambers 16 and 17. These cl'iambers are in communication at their lower ends through openings 18 between the bottom wall'of the receptacle 13 and the depending portion of the partition 15, and are also in communication above said partition.

The inlet chamber 16 of the first drum 5 of the series is in comnninication with the pipe 7 through which the spirits, vapor and water of condensation from the still 2 flows thereinto. The pipe 7 is arranged opposite and in line with the partition 15, which serves as a baffle against which the entering fluids strike, the vapor rising and passing over the partition into the upper portion or vapor containing space of the discharge chamber 17 while the spirits and water of condensation flow downwardly and pass through the openings 18 from the chamber -16 to the chamber 17, the result being that the spirits and water of condensation are cooled to a further extent, while the vapor contained in the top portionof the drum is also cooled and condensed to a greater or less extent.

Any portion of the vapor contained in each drum which is not condensed flows through the pipe or tube 9 into the next drum and is wholly or partially condensed therein, the arrangement being such that all of the vapor will be condensed in the successive drums before the discharge of the condensates from the drum 6*, while the spirits and water flow from thespirits and water containing spaces of each drum through the pipe or tube 10 to the equiva lent spaces of the other drums in turn,

the air discharges through the pipe 11 and from which the spirits and water of con- 7 densation are drawn off through the pipe 12 for subsequent separation in any of the well known ways and storage of the spirits for final disposition. It will be evident that as the drums of the auxiliary condenser'are thoroughly cooled the "apors escaping from the spirits will be condensed and recovered, thus preventing their loss, while at the same time the spirits will be cooled'to such a degree before discharge as to prevent evaporation of the volatile constituents thereof on coming into the air. A considerable portion of the spirits is saved. and greater economy secured, in the distillation of turpentine. in large plants.

The cooling water may be supplied to the apparatus in any preferred manner, but in the present instance I have shown a valve water supply pipe 18- which communicates with the tank 4, from which the water discharges through a valved outlet 19, so as to maintain a gradual and uniform circulation of the water. The pipe 18 is connected by cross pipes 20 with nozzles or injectors 21 which extend upwardly into the domes of the drum, so as to discharge cooling water directly into the space bounded by each drum, whereby a greater efficiency of cooling action is secured. A vent outlet 22 extends upwardly through each drum, and communicates at its lower end with the dome and projects at its upper end through the top of the drum into the tank, said upper end of the vent pipe being provided with a valved outlet or vent cook 23, so as to establish an upward circulation of water through the drum, thus keeping the body of the drum, interiorly as well as exteriorly, cooled to a desired low temperature.

I claim 1. An auxiliary condenser for turpentine distilling apparatus including a plurality of communicating condensing vessels, each partitioned to provide spaces for the condensates and vapor, the like spaces of said vessels communicating with each other, the first vessel of the series being provided with an inlet for the condensates and vapor, and the last vessel of the series being provided with separate outlets for the condensed spirits and the air;
